IM PROVED STUMP- EXTRACTOR..

Specification forming part ot'Letters Patent No. 39,375, dated August 4,1863; autedated December 8, 1861.

To all whom, it may concern.-

Be it known that I, J. BEACHLER, of Anderson, Madison county, and Stateot Indiana, have invented a new and Improved Stump-Extractor; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making a part of this specification, in which- Figure l is a top view ofthe improved stnmpextractor. Fig. 2 is a longitudinal section throughFig. 1, in the vertical plane indicated by the red line thereon. Fig. 3shows a sliding block ot' one of the carriage-wheels,

and the levers for operating it.

Similar letters of reference indicate corresponding parts in the threefigures.

This invention relates to improvements in machines for pulling` upstumps, roots, Src., for clearing land.

To enable those skilled in the art to make .md use my invention, I willproceed to describe its construction and operation.

A A represent two horizontal transverse beams, and B B are the end orupright frames, which, together with the beams A A, form a trestle forsupporting the machinery used in extracting stumps. The beams A A, aswell as the frames B B, are made of very heavy timber for giving thedesired strength, and the beams at the bottoms of frames B B are madewide, so that they will not be liable to sink into the ground during theoperation of pulling up a stump.

C C represent two carriage-wheels having The axles c c ot' these wheelsC C are secured to and project out horizontally from vertically-slidingblocks ci a, which work in suitable guides, I) b, secured to the middleuprights of the frames B B. One block a and guide b of one frame B areshown in Fig. 3 of the drawings, the wheel being removed from its axlec. To the sliding blocks a a short rods d d are pivoted, the upper endsot' which rods are again pivoted to crank-arms e e on the ends of arock-shaft, D, which passes transversely across the machine, eitherbelow the bars A A or above these bars. This rockshaft D is in ahorizontal position, and it has its end bearings in the two uprightframes B B. The cranks e e project outside of each frame B. Two longarms, ff, are secured to and project down from the rock shaft D, insideof and near the frames B B, and to these arms j' f long rods g. g areattached., which proceed forward and are connected at their front endsto the rear end ot' a longitudinal sliding rod, E. Bod E is connected bymeans of straps g g to the straight portion of a curved tongue, G, whichis secured rigidly to the front beam A, 'as shown in Figs. 1 and 2 ofthe drawings. The tongue Gr is curved downward from beamA, and the frontor straight end of this beam is nearly in a horizontal plane with thelower beams of frames B B. The straps g g allow the rod E to receive anend-play its full length, and this rod E is pivoted at its front end tothe axle H of guide-wheels H H, when the machine is to be drawn aboutfrom place to place.

The draftpole I, to which the team is attached, is connected to theaXletree H, and when the machine is in a proper position for operationthe king-bolt which connects the axle of the front wheels to the rod Eis removed, and the team is hitched to the outer end of the sweep J.

Means are provided for xing the rod E, either when it is pushed back toits fullest eX- tent or when it is drawn out toits fullest extent. Thisis effected in the following manner: A pin, t', passes down through thetongue G, near its front end, and enters the holes j j in the rod E,when one or the other hole is brought under the pin i. This kpin i' is-pivoted at its upper end to the lever k, and this lever 7c is actedupon by a spring, lo', which forces the pin i downward. l l arebrace-rods for stift'- ening the tongue G. Now, from this description itwill be seen that when the rod E is free to move and the horses hitchedto the draft-pole I and started `forward the rod E will be moved outwarduntil the pin is forced into the back hole j. This movement of rod Ewill draw the arms f f forward and depress the cranlzs'e e, whichoperation will depress the blocks a a and mount the trestle on thewheels C C. The machine may now be moved about from place to place onthe carriagewheels. Then, when it is desired to throw the machine ott'of its wheels C C, the pin 'i is raised so as to free the rod E, andthis rod E is pushed back by backing the horses. This operation willelevate the wheels C (l and allowr the trestle to rest on the ground ina position for operation.

The mechanism for extracting the stumps is mounted on the horizontalbars A A, and is constructed as follows: K represents a largescrew-shaft, which passes perpendicularly through a collar, L, throughwhich this screw-shaft is allowed to play loosely. The collar L issecured on top of the bars A A and in the middle ot' these bars. Aneyeis formed on the lower end of screw K andV a square head on the upperend of this screw. To the eye on the lower end of screw K a chain, N, ofa suitable length and strength, is attached, which chain is furnishedwith coupling-hooks for attaching it to the stump to loe pulled up. Theupper end of screwK is tapped through a nut, m, which is rigidly securedinto the sweep or lever J, as shown in Figs. l and 2 of the drawings.Now, when the sweep J is turned round, the screw K will be iorcibyelevated. To depress the screw K again, a crank, M, is used, (shown inFig. 2 of the drawings,) and the sweep J allowed to remain stationarywhile the screw is depressed. The sweep J should be of such a length asto allow the team to pass the end of tongue G without walking over it.

The machine is represented in Fig. 2 in a working position, and also inred lines in a position when mounted on wheels, ready fortransportation.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The sliding blocks a a, to which the wheels C C are attached, and therods d d, cranks e e, shaft D, and arms f f, in combination with therods g g, draft-rod E, and holding-pin c', all arranged and operating asand for the purposes herein set forth.
